A barely used cell phone. A destroyed computer. No social media accounts. A final week spent alone playing video games. In the aftermath of the horrific shooting at Sandy Hook Elementary School, Adam Lanza left behind very little in the way of clues for investigators to piece together what made him tick, reports the Hartford Courant. "He killed the only person who really knew him well ... so figuring out the why here is going to be difficult," said one investigator.

Lanza had thousands of dollars worth of video games in a basement bedroom, one of two he used in the house, but appears to have preferred playing online anonymously. So far, Lanza's online footprint has mostly turned out to be hoaxes, with investigators promising arrests for those responsible. Detectives have been scouring the 4,000-square-foot home Lanza shared with mother Nancy, and while his shattered computer would have been a good bet for clues, "it is hard to put Humpty Dumpty together again," says one expert. Investigators say the official report on the shooting is still "several months away,” according to the Connecticut News blog.
